Question

2) x– 5y = 8, 3) 5a– 3b= 14, 2x+ 4y = 30; 2a + b = 10; 2) 2x– y= 1, 4) 2x– 3y = 2, 7x – 6y= –4; 4x – 5y = 1

Answer 1

Ответ:

2) x - 5y -8=0

3) a = 14 дробь 5 + 3 дробь 5 b ,b = 0

x+2y - 15=0

a=5-1дробь 2 b , b =0

2) 2x-y-1=0

Answer 3

It seems like you've provided a system of linear equations with variables x, y, a, and b. The system consists of four equations:

1. $x - 5y = 8$
2. $5a - 3b = 14$
3. $2x + 4y = 30$
4. $2a + b = 10$
5. $2x - y = 1$
6. $2x - 3y = 2$
7. $7x - 6y = -4$
8. $4x - 5y = 1$

You can solve this system of equations to find the values of the variables x, y, a, and b that satisfy all the equations. To solve such a system, you can use methods like substitution, elimination, or matrix algebra. Which method would you like to use, or do you need help with a specific part of the solution?
